Programmable Dual Section Charging Chip Solution

Programmable Dual Section Charging Chip Solution

The programmable dual section charging chip includes a complete charging termination circuit, automatic recharging, and a preset charging voltage of 8.4V with an accuracy of ± 1%. It integrates multiple functions such as anti backflow protection, output short circuit protection, chip and battery temperature protection. It can adapt to the current supply capacity of the adapter to ensure that the input adapter does not experience overload, making it suitable for various DC devices and standard USB charging devices. The programmable dual section charging chip integrates a 20V power MOSFET. It can withstand voltages up to 20V and integrates undervoltage and overvoltage protection functions, with high reliability, without the need for additional surge or overvoltage protection devices.
